摘要： An improved method and structure for purification of an acid gas stream by using raw fuel gas as a stripper to remove the BTEX and VOCs from the liquid amine stream. The improved method is particularly useful for purification of acid gas streams with BTEX contaminant levels in excess of environmentally acceptable levels for standard processing. Raw fuel gas is utilized at moderate temperatures and pressures, the uptake of BTEX and VOCs reduces the level of these compounds in the waste amine stream to environmentally acceptable levels, and the remaining contaminants may then be dealt with by ordinary means. Levels of H2S and CO2. in the liquid amine stream are also reduced.

摘要： In a method of separating carbon dioxide from a gas mixture, a liquid solvent flows down an array of vertical wires with the gas mixture flowing over the liquid. Once on the wire, the liquid quickly breaks up into drops of varying sizes, with each size moving down the wire at a different velocity. Large, faster moving drops overtake the small, slower moving drops to form even larger drops. As the drops fall, new drops are created behind the falling drops. Consequently, drops of a large range of sizes are forming, colliding, and mixing as they travel down the wire. During this process, gas molecules that have adsorbed onto the liquid surface are mixed into the interior of the solvent, resulting in highly effective mass transfer and gas absorption. This enhanced mass transfer allows greater flexibility in the choice of solvent and in the system design.

摘要： The exhaust gas purification device according to the present invention utilizes two NOx absorbents in order to remove NOx from the exhaust gas of an engine operated at a lean air-fuel ratio. The NOx absorbents are disposed, in series, in the exhaust passage of the engine and a nozzle for supplying a reducing agent is disposed in the exhaust passage at a position between the two NOx absorbents. Further, the device includes switching valves for changing the direction of the exhaust gas flow in the exhaust gas passage. When the switching valves are set to direct the exhaust gas flow to one direction, the exhaust gas first flows through one of the NOx absorbents (first NOx absorbent), and after passing through the first NOx absorbent, the reducing agent is supplied to the exhaust gas before it flows into the other NOx absorbent (second NOx absorbent). Thus, the first NOx absorbent absorbs NOx in the exhaust gas, and the NOx absorbed by the second NOabsorbent is released from the second NOx absorbent. When the switching valves are switched, the exhaust gas flows in the opposite direction, and flows through the second NOx absorbent and the first NOx absorbent in this order. In this case, the second NOx absorbent absorbs NOx in the exhaust gas, and the NOx absorbed by the first NOx absorbent is released and reduced to N2. Therefore, by reversing the direction of the exhaust gas periodically, the absorbing operation of NOx and releasing/reducing operation of NOx are performed by two NOx absorbents alternately. Thus, it becomes possible to remove NOx in the exhaust gas continuously while the NOx absorbents are prevented from being saturated by the absorbed NOx.
摘要翻译：根据本发明的排气净化装置利用两个NOx吸收剂来从以稀空燃比运转的发动机的废气中除去NOx。 NOx吸收剂串联设置在发动机的排气通道中，并且用于供给还原剂的喷嘴设置在排气通道中的两个NOx吸收剂之间的位置。此外，该装置包括用于改变排气通道中的排气流的方向的切换阀。当切换阀被设定为将废气流引导到一个方向时，废气首先流过NOx吸收剂之一（第一NOx吸收剂），并且在通过第一NOx吸收剂之后，还原剂被供给到排气气体在其流入另一个NOx吸收剂（第二NOx吸收剂）之前。因此，第一NOx吸收剂吸收废气中的NOx，并且由第二NO吸收剂吸收的NOx从第二NOx吸收剂释放。当切换阀切换时，排气沿相反方向流动，并且依次流过第二NOx吸收剂和第一NOx吸收剂。在这种情况下，第二NOx吸收剂吸收废气中的NOx，并且由第一NOx吸收剂吸收的NOx被释放并且还原成N2。因此，通过周期性地反转排气的方向，NOx的吸收运转和NOx的释放/还原运转由两个NOx吸收剂交替进行。因此，可以连续地除去排气中的NOx，同时防止NOx吸收剂被吸收的NOx饱和。

摘要： A process is provided for removing CO2 and/or H2S from a gas mixture containing as impurities CO2 and/or H2S and at least one other impurity selected from the group consisting of a cyanide and ammonia. The process includes contacting at least a portion of the reflux stream from the overhead vapor from a stripping column of an acid gas removal solvent (i.e., alkanolamine) treatment plant with an anion exchange resin to remove corrosive impurities. The ion-exchanged reflux stream is then recycled to the top of the stripping column or into the bulk circulating acid gas removal solvent (i.e., alkanolamine) passing from the bottom of the stripping column.

摘要： Hydrogen fluoride production apparatus removes phosphate rock dust from a hot gas mixture exhausted from a phosphate rock defluorination kiln; cools the hot gas mixture in a heat exchanger to a low enough temperature that it can be brought into contact with acid-resistant polymeric materials without destroying them; uses a water spray scrubber for further cooling the gas and absorbing the fluoride values as HF-rich liquor; and pumps the HF liquor to a holding tank. One such plant uses a gas tube steam boiler as the heat exchange and has several series-connected scrubbers to extract the fluorine values from the kiln exhaust so that the residual gas mixture can be exhausted into the atmosphere without exceeding permissible fluorine value levels. In this arrangement water is fed into the scrubber furthest from the boiler to extract HF from the process gas, and an HF-laden process liquor is fed out of the furthest scrubber into the second furthest scrubber, where it is sprayed into the gas stream. This counter-current flow arrangement continues until one reaches the scrubber closest to the boiler and extracts the most concentrated process liquor from a sump nearest the boiler.
